The Mercedes-Benz OM642 engine is a 3.0-liter, 72° 24-valve, aluminum block diesel V6 engine manufactured by the Mercedes-Benz division of Daimler AG as a replacement for the Mercedes-Benz inline-5 and -6 engines.〔(【引用サイトリンク】title=05_kompact_en.doc )〕 The engine features common rail fuel injection and a variable nozzle turbocharger. The injection system operates at , while the compression ratio is 18:1.〔 The engine features a counter-rotating balance shaft mounted between the cylinder banks to cancel the vibrations inherent to the 72 degree V6 design, and the crankpins are offset by 48 degrees to achieve even 120 degree firing intervals. In some heavy vehicle applications, Mercedes' BlueTec AdBlue urea injection is utilised for NOx reduction.〔(Consumer Reports: What is BlueTec? )〕 In lighter vehicle applications, a NOx storage catalyst captures nitrous oxides, which are periodically purged (decomposed) by running the engine slightly rich. A particulate filter lowers soot, making this engine ULEV certified.〔〔(Motive Magazine ULEV certification, Diesel Car Bomb BlueTec )〕 Engine mass is . Power output is and of torque.〔 For the 2007 model year, torque is raised to 540 Nm. ==Implementation== Vehicles using this engine include: * Dodge / Freightliner Trucks / Mercedes-Benz Sprinter (2006–Present) * Jeep Grand Cherokee WK/WH (2005-2012 (Europe) 1-20072-2008) * Mercedes-Benz C320 CDI (2005–Present) * Mercedes-Benz E280 & E320 CDI/Bluetec (2007-2009) models 211.02 & 022 * Mercedes-Benz C350 CDI (2009–2009) * Mercedes-Benz E350 CDI/Bluetec (2010–Present) Models 212.024 * Mercedes-Benz G350 CDI/Bluetec (2010–Present) * Mercedes-Benz R320/350 CDI/Bluetec (2007–Present) Models 251.122 & 125 * Mercedes-Benz ML320/350 CDI/Bluetec (2007–Present) Models 164.122, 125 & 024 * Mercedes-Benz GL320/350 CDI/Bluetec (2007–Present) Models 164.822, 825, & 824 * Mercedes-Benz S320/350 CDI/Bluetec (2005–Present) Models 221.183 * Chrysler 300C (2006-2011) (Europe and Australia only) * Mercedes-Benz Vito Van 120 cdi and Vito 204 Sports (2006–Present UK) 1 EMEA 2 North America 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mercedes-Benz OM642」の詳細全文を読む スポンサード リンク
